WASHINGTON -- In today's segmented America, Michael Crichton's new novel "State of Fear" might seem to be just reading for red states. Granted, a character resembling Martin Sheen -- Crichton's character is a prototypical Hollywood liberal who plays the president in a television series -- meets an appropriately grisly fate. But blue states, too -- no, especially -- need Crichton's fable about the ecology of public opinion.

     "State of Fear,'' with a first printing of 1.5 million copies, resembles Ayn Rand's "Atlas Shrugged'' -- about 6 million copies sold since 1957 -- as a political broadside woven into an entertaining story. But whereas Rand had only an idea -- a good one (capitalism is splendid), but only one -- Crichton has information. ``State of Fear'' is the world's first page-turner that people will want to read in one gulp (a long gulp -- 600 pages, counting appendices) even though it has lots of real scientific graphs, and footnotes citing journals such as Progress in Physical Geography and Transactions -- American Geophysical Union. 

     Crichton's subject is today's fear that global warming will cause catastrophic climate change, a belief now so conventional that it seems to require no supporting data. Crichton's subject is also how conventional wisdom is manufactured in a credulous and media-drenched society.     

     Various factions have interests -- monetary, political, even emotional -- in cultivating fears. The fears invariably seem to require more government subservience to environmentalists, and more government supervision of our lives.

     Crichton's villains are environmental hysterics who are innocent of information but overflowing with certitudes and moral vanity. His heroes resemble Navy SEALs tenured at MIT, foiling the villains with guns and graphs.
